The crankpin v is connected with the vertical reciprocating rod 11 in the following manner: Two separable jaws or plates 26 and 27 having V- shaped grooves 28 and 29 therein are adapted to embrace said rod 11, the groove 28 being provided with a recess, in which is retained a facing of fiber 30 or other suitable frictional material. The groove 29 on the plate or jaw 27 is provided with a similar recess, in which is first placed an L-shaped plate 31 and also a facing 32 of fiber or other similar material.

As means for adjusting the relation of the L-shaped plate 31 in relation to the jaw 27 I provide screws 33 at the upper and lower ends of said jaw 27. These screws pass through low boxes or projections 34, upon which rests a spring-plate 35. Passing through suitable openings in the jaws 26 and 27 is a U-shaped bar or support 36, to which is pivoted a camlever 37 by means ofa bolt or other bearing 38. The cam-lever 37 has a slightly-flattened portion 39, which is adapted to bear against the central portion of the plate 35 when the lever is pulled outwardly in a position shown in Fig. 3. When the said lever 37 is pushed inwardly, the more rounded portion of the end thereof will force the plate 35 inwardly, and thereby cause the jaw 27 to engage the rod 12 with suitable pressure.

As means for holding the lever 37 in its operative position are provided spring-jaws 40, which are fastened to the plate 27 and frictionally engage the lever 37 when, the same is forced inward. When the lever. 37 is in its inner'position, the requisite pressurewill be maintained between the jaws 26 and 27 and the rod 11. As means for maintaining the support 36 in engagement with the jaws 26 the usual set-nuts 44 are provided. From the rear of the jaw 26 projects a stud or bearing 45, which is connected with the crank-pin 25 on the disk 24 by means of a link or pitman 46.

It will now be seen that as the shaft 19 is rotated the crank-disk 24 will also be rotated therewith, which will communicate a reciprocating motion to the jaws 26 and 27 through the crank-pin 25, the pitman 46, and bearing 45.

The means for supplying the filling to the bag or cushion-casing 8 comprises the following parts: Beneath the machine is placed a box or reservoir 47, into which projects a conduit or pipe 48, which connects with a centrifugal blower .49. The pipe 48 continues through said blower and enters a hopper 50. Thelower end of .the hopper 50 is attached to the pipe or conduit :14, which connects at its lower end with the interior of the bearing 10. The centrifugal blower 49 is driven through the means of a suitable pulley 53, carried by the shaft 19, and by the driving-belt 54. Carried by the rod 11 is an adjustable stop 51,wl1ich is adapted'to engage with the upper end of an elastic cushion or bushing 52, of rubber or similar material, which rests upon the bearing 9. This cushion is adapted to form a yielding stop for the rod 11 when the jaws of the clamp are released and said rod thereby allowed to drop, so that the plunger or rammer 12 may be brought into the lower portion of the bag or casing 8.

The operation of the parts of the improved machine as thus described is as follows: Assuming that the bag or cushion 8 has been .placed in position within the mold 7 and the parts thereof closed and the opening in-the casing 8 has been placed about the lower end of the bearing 10, the lever 37 is then forced inwardly, which will produce the required pressure to cause the facings 30 and 32 to frictionally engage the surfaces of-the rod 11.-

The machine is then started by causing the belt 23 to be shifted unto the fast pulley 20. The rotation of the shaft 19 will then cause the jaws 26 and 27, which embrace the rod 11. to'reciprocate vertically. As the blower 49 is now also in operation, the filling material will be withdrawn from the reservoir 47.and carried into the hopper 50, from whence it will pass through the pipe.14 into the interior of the bearing 10 and thence through the lower end thereof into the interior of the bag or casing 8 through the space between said bearing and thesides of the plunger or rammer 12. The filling material willtherefore be continuously fed to said bag or casa ing and asthe rammer 12'reciprocates will 7 be firmly packed into position. As the bag or casing 8 fills it is obvious'that the portion of the filling material to be rammed into position reaches a higher and higherlevel within the bag or casing; but'the rammer is accommodated to this change in level by reason of the fact of the frictional engagement of the reciprocatingjaws 26 and27 withthe rod 11 that is to say, when the rammer12 strikes the material within the casing8 with a force above a certain amount the rod 11 will slide within said jaws and assume a reciprocating position slightly higher than its previous one, and as the casing fills the position of the rammer 12 will be constantly changed until the said casing is sufliciently filled.

It will thus be seen that after the-machine is once started the filling material is automatically supplied to the interior of'the casing and rammed home without anyfurther manipulation, thus providing a hard, firm, and even packing for the cushion or other article which is being manufactured.

Having thus described one form of-thisinvention, it will be seen that a vmachinezhas been produced which after once being started is automaticin its action .and causes the material to be placed within the casing or bag and rammed or packed into position witha minimum of time and labor and with ,the best resultfin the finished product; but it will also be obvious that certain changes may be made in the form and arrangement and proportion of parts and mechanical equivalents may be substituted without departing from the spirit and scope of the invention; but

Whatis claimed, and desired to be protected by Letters Patent of the United States, is

1. In a filling and packing machine, the combination with a reciprocating plunger or rammer, means for giving a positive downward thrust to said rammer, and means for allowing the recession of said rammer as the material in the receptacle being filled ascends in height.

2.
